All change: protein conformation and the ubiquitination reaction cascade

The structures of enzymes that collectively modify proteins by covalent addition of ubiquitin-like protein moieties have provided significant insights into the regulatory pathways they compose and have highlighted the importance of protein flexibility for the mechanism and regulation of the ubiquitination reaction.

Fatty acids change the conformation of uncoupling protein 1 (UCP1).

UCP1 catalyzes proton leak across the mitochondrial inner membrane to disengage substrate oxidation from ATP production. It is well established that UCP1 is activated by fatty acids and inhibited by purine nucleotides, but precisely how this regulation occurs remains unsettled. Although fatty acids can competitively overcome nucleotide inhibition in functional assays, fatty acids have little ef...

Allostery without conformation change: modelling protein dynamics at multiple scales.

The original ideas of Cooper and Dryden, that allosteric signalling can be induced between distant binding sites on proteins without any change in mean structural conformation, has proved to be a remarkably prescient insight into the rich structure of protein dynamics. It represents an alternative to the celebrated Monod-Wyman-Changeux mechanism and proposes that modulation of the amplitude of ...
